--- - |2+ Background Early childhood intervention (ECI) centres in Spain recently initiated a process of change towards the adoption of family‐centred practices (FCPs). Knowledge about the extent to which practitioners' use FCPs is needed. The psychometric properties of the Spanish version of the FCPs scale were examined. Method A convenience sample of 105 families of children with developmental delays attending three different ECI centres in Spain completed the FCPs scale and provided information about the ECI centre characteristics and practices, caregiver self‐efficacy beliefs, and family and child demographic information. Results The Spanish version of the FCP scale was found to be both reliable and valid. FCPs were correlated with self‐efficacy beliefs, parents' involvement in their child's ECI program and family decision making. Conclusion The FCP scale provides practitioners with useful information about their practices, but also has capacity‐building consequences for families. The study is a first step for examining the use of FCPs in Spain. - Journal of Applied Research in Intellectual Disabilities, Volume 31, Issue 5, Page 851-861, September 2018.
